Hi
I designed 1:2 unequal wilkinson power divider for array antenna with Er=2.2 h=.254mm in ADS
The impedences for power divider are z0=30ohm z1=Z0*sqrt(k*(1+k^2))=34.15(90deg) z2=z0*sqrt((1+k^2)/k^3)=54.12(90deg) z3=z0*K=26.74 z4=z0/k=33.66 and R=61.6ohm..
The distance between the elements...
I need to design 8X8 phased array antenna initially i designed 4X4 array antenna with SLL is low .. but i need SLL=20db .. Can u give me the formula for taylor series for rectangular array with SLL=20db please
hi
i want to design switched line phase shifter for 8X8 microstrip patch array antenna at 35GHZ using transmission lines. Can anybody give idea about how to design it in ADS ?
Hi
Thanks for your reply..This is 4X4 patch array antenna . The gain is 18.33db and first sidelobe is 4.335.element spacing is .9lamda.. How to get 25db sidelobe suppresion?
hi i ve designed 4X4 microstrip patch array antenna at 35GHZ using ADS
the parameters i m getting are
returnloss =-25.86
directivity is 18.56 dbi
gain= 11.23dbi
gain is very low
so i want to ask that what is the range of the gain and how can i increase the gain my antenna
plz guide me
